There is a commonly held opinion that, without foreign aid, the Red Army would have hardly any trucks at all and would not be able to execute strategic offensives. Indeed, if you compare the amount of trucks produced in the USSR during the war and the amount of trucks shipped in, the amount of the latter is much greater. This creates the impression that the Red Army was almost entirely dependent on foreign aid for trucks.
However, it is incorrect to take into account only what was produced during the war without looking at what was already in stock. At the start of the war trucks in agricultural use were confiscated en masse for military use. This injection of new trucks ensured that the majority of the Red Army's trucks were still domestic even by the end of the war.

As the war went on, the amount (if not the proportion) of domestic trucks in the Red Army increased, so even at reduced capacity domestic industry managed to make up for losses and more. Even at the very end of the hostilities in Europe, Lend Lease trucks composed less than a third of the Red Army's truck fleet.
